Abstract
Abstract A lubricant composition for forging or extrusion comprising a mixture of: (A) at least one compound selected from among phosphoric acid and salts thereof, (B) at least one compound selected from among boric acid and salts thereof, (C) at least one compound selected from among carbonates, nitrates, sulfates and hydroxides of alkali metals, and (D) a phyllosilicate, the mixture containing the compounds (A) to (C) in amounts, calculated as oxides, of 40 to 44 mole % of P2O5, up to 9 mole % of B2O3 and 30 to 60 mole % of M2O wherein M is an alkali metal, respectively.
